CHARLES E. TROWBRIDGE, OF WVHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THEWHITINSVILLE SPINNING RING COMPANY, OF SAME PLACE.

SPINNING-RING.

SPECIFICATION forming part of Letters Patent No. 438,660, dated October21, 1890.

Application filed April 8, 1890. Serial No. 347,042. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. Tnow- BRIDGE, of VVhitinsville, county ofWVorcester, State of Massachusetts, have invented an Improvement inSpinning-Rings, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention, relating to spinning-rings, has for its object tocombine with a spinningring having an annular groove in its body atraveler-clearer having a portion inclined in the direction of themotion of the traveler on the race of the ring, the traveler-clearerhaving a spring-like portion to clasp the ring in its annular groovedpart.

I have shown my invention as applied to that class of ring known asdouble race, it having an annular body with a raceway at each endthereof. The clearer shown consists of a piece of spring-wire bent tosubstantially surround the body of the ring, one end of the ring beinginclined upwardly near the line of progress of the traveler, as clearlyshown in application Serial No. 347,041. To retain the clearer inposition upon the body of the ring, the latter has an annular projectionwhich, as shown, is located substantially midway between the raceways,thus leaving a groove both above and below said annular projection toreceive the spring part of the clearer, the said projection preventingthe clearer rising from its true working position.

One part of my invention consists in a spinning-ring having an annulargroove or depression at its outer side, combined with a traveler-clearerconsisting of a portion inclined in the direction of the motion of thetraveler on the race and having a spring-like portion to clasp the ringin the said annular groove to operate as will be described; also, in aring composed of a body having raceways at its opposite ends and anannular projection between the said raceways, combined with atraveler-clearer consisting of a portion inclined in the direction ofthe motion of the traveler on the race, and having a springlike portionto clasp the ring between the said annular projection and one of theraces thereof, as will be described.

Figure 1 in side elevation represents a ring embodying my invention withaclearer thereon. Fig. 2 is a section through one side of the ring. Fig.3 is a view of the ring shown in Fig. 1,1ooking at the same from theright; and Fig. 4: is a modification showing a section of the ringwherein the body is provided with an annular projection at one side.

Referring to the drawings, the body of the ring has at each end a race,as a b, on which may run any usual traveler (Z, and substantially midwaythe said raceways the ring is provided with an annular projection b,leaving a groove above and below the same into which a part of thetraveler-clearer may be sprung, according to which end of the ring isused uppermost.

The traveler-clearer herein shown consists of a piece of wire-likematerial 0, inclined upwardly in the direction of the movement of thetraveler on the race of the ring to operate as described in myapplication Serial No. 347,041, the said upwardly-inclined portion beingpart of a spring-like clasp c,which partially embraces the ring enteringthe groove thereof between the projection and the under race upon whichthe traveler is not running.

The ring will be held in any usual ringholder, which latter will beattached to the rail in any usual manner.

The annular projection b may be made upon the outer and inner sides ofthe body of the ring, as in Fig. 2, or may be solely upon the outer sideof the ring, as in Fig. 4, the said annular projection, whether upon oneor both sides of the ring, in addition to keeping the traveler-clearerin proper position with relation to the ring, also serving to strengthenthe ring, so that the body portion thereof is less liable to spring whenhardening.

I claim 1. A spinning -ring having an annular groove or depression atits outer side, combined with a traveler-clearer consisting of a portioninclined in the direction of the motion of the traveler on the race, andhaving a spring-like portion to clasp the ring in the said annulargroove, to operate substantially as described.

2. A ring composed of a body having raceways at its opposite ends and anannular projection between the said raceways, combined In testimonywhereof I have signed my with a traveler-clearer consisting of aportionname to this specification in the presence of inclined in the directionof the motion of the two subscribing Witnesses.

traveler on the race, and having a spring-like CHARLES E. TROWBRIDGE. 5portion to clasp the ringbetween the said an- Vitnesses:

nular projection and one of the races thereof, WVILLIAM H. WVHITIN,

substantially as described. ARTHUR F. WHITIN.
